Abstract

We construct two series of linear codes over finite ring Fq[x]/(x2)\mathbb{F}_{q}[x]/(x^2) and Galois ring GR(p2,m)GR(p^2,m) respectively reaching the Griesmer bound. They derive two series of codes over finite field Fq\mathbb{F}_{q} by Gray map. The first series of codes over Fq\mathbb{F}_{q} derived from Fq[x]/(x2)\mathbb{F}_{q}[x]/(x^2) are linear and also reach the Griesmer bound in some cases. Many of linear codes over finite field we constructed have two Hamming (non-zero) weights.
